Abstract
The utility model provides a pivot provided with a bearing frame and two retaining points; a first convex retaining block and a second convex retaining block are respectively arranged on two side surfaces of a folding sheet which is arranged on the bearing frame and can be penetrated by a shaft part; furthermore, a first position limit element and a second position limit element which rotate together with the shaft part are respectively arranged on the two side surfaces of the folding sheet; each position limit element is respectively provided with a first retaining part and a second retaining part; therefore, when the pivot is opened to the maximum angle, the first retaining part pushes through the first retaining block and the second retaining part pushes through the second retaining block so as to jointly limit maximum rotation angle of the rotation shaft of the pivot and the bracket corresponding to the base, thus improving the structural reliability.
Description
Technical field
The utility model is about a kind of hinging structure of folding-type electronic device, the pivot of the two retaining points of especially single bolster.
Background technique
Folding-type electronic device, for example notebook computer etc. has a body and a display screens, connects with pivot therebetween, make display screens to be covered on relatively and be operating position on the body, perhaps display screens relatively body outward winding and be the enable possition of use.
Because the weight of display screens is damaged pivot for preventing that transition from opening, regular meeting is provided with the retaining dot structure in pivot, prevent the transition unlatching with the restriction opening angle.
This retaining dot structure is more than forming a block on the bolster of rotating shaft, and the limit element that a periphery evagination forms a fanning strip is set in rotating shaft, utilize limit element and rotating shaft together to rotate, when fanning strip is kept out block on the bolster, promptly limit the angle of swing of rotating shaft, and then prevent excessive unlatching.
This kind known configurations only has a retaining dot structure on single bolster, its bracing force is not enough sometimes, causes block to fracture, or fanning strip damage and arrive invalid.The quantity of keeping off point for increase with the present practice, is to increase to hold a sheet and a limit element to improve support force again, to improve the quantity of keeping off dot structure.But increase owing to hold the quantity of sheet, will make the assembling of pivot increase work procedure, and the cost rising, remain in fact to be improved.

Embodiment
See also Fig. 1 and Fig. 2, the utility model provides first kind of embodiment of the pivot of the two retaining points of a kind of single bolster, system is used in the folding-type electronic device with a body and a display screens, opens and closed action to provide this display screens to produce this body.The pivot main structure comprised a rotating shaft 10, a support 20, a pedestal 30, a bolster 40, first and second limit element 51 and 52, a friction plate 60, a shell fragment group 70, one group recessedly take turns 81 and cam 82, an and end cap 90.
Can cooperate Fig. 3, bolster 40 has one folding piece 41, offers a circular hole 42 on it, and this circular hole 42 passes for axial region 11, simultaneously, is arranged with the first outstanding block 43a and the second block 43b in tabs 41 bi-side near circular hole 42 marginal positions.And first and second limit element 51 and 52 is the bi-side that are divided into tabs 41, each limit element has a non-circular hole 511,521 and can together rotate with this rotating shaft 10 for axial region 11 passes, and each limit element periphery extends outward first blocked part 512 and second blocked part 522; First blocked part 512 and second blocked part 522 are to be located at periphery, and are first fanning strip and second fanning strip that a disk extends outward.First blocked part 512 can offset with the first block 43a, and second blocked part 522 can offset with the second block 43b, with the rotation angle of common restriction rotating shaft 10 and support 20 relative pedestals 30.
In addition, also be provided with on the axial region 11 of rotating shaft 10 friction plate 60, shell fragment group 70, and recessedly take turns 81 and cam 82.
Recessedly take turns 81 and the auto-closing function that provided of cam 82, the preceding case that can " have the pivot that closes entire function automatically " referring to claimant's TW-M295419.
Referring to Fig. 4 and Fig. 5 is action specification of the present utility model.Fig. 4 is shown as the display screens of folding-type electronic device and the position of body closure, first blocked part 512 of first limit element 51 and second blocked part 522 of second limit element 52 can not contact with the first block 43a and the second block 43b at this moment, so support 20 can be along direction of arrow rotation among the figure.
When display screens is relative with body when outwarding winding, the axial region 11 of rotating shaft 10 can drive first limit element 51 and 52 rotations of second limit element, conflict with the first block 43a and the second block 43b respectively to two blocked parts 512 and 522, position shown in Fig. 5 and Fig. 5 A is to reach the rotation angle of common restriction rotating shaft 10 and support 20 relative pedestals 30.
The utility model is provided with two retaining dot structures on a bolster 40, to improve the ability of restriction folding-type electronic device display screens opening angle.Simultaneously, owing to only on a bolster 40, be provided with, also can reach cost-effective effect.
Referring to Fig. 6 and Fig. 7 is second kind of embodiment of the present utility model, and wherein the second block 43b on the tabs 41 of bolster 40 is located at tabs 41 sides near circular hole 42 marginal positions, and the first block 43c is the extended kinks in tabs 41 edges.In addition, second limit element 52 is identical with a last embodiment, and second blocked part 522 on it is to be located at periphery, and is second fanning strip that a disk extends outward; And first limit element is first blocked part 513 that forms on support 20.
Shown in Fig. 7, when rotating shaft 10 and support 20 relative pedestals turned to maximum angle, conflicted with the first block 43c and the second block 43b respectively in two blocked parts 513 and 522, to reach common restriction rotating shaft 10 and support 20 maximum angle that rotates relative to pedestal.
In addition, at Fig. 8 and Fig. 9 is the third embodiment of the present utility model, its roughly with aforesaid first kind of implementation of class seemingly, comprised a rotating shaft 10, a support 20, a bolster 40, first and second limit element 51 and 52, a friction plate 60, a shell fragment group 70, one group recessedly take turns 81 and cam 82, an and end cap 90.
The 3rd embodiment and first embodiment's main difference point are that the first block 43a and the second block 43b on bolster 40 tabs 41 runs through 45 formations of perforation near circular hole 42 marginal positions with a projection 44.First and second limit element 51 and 52 peripheries extend outward first blocked part 512 and second blocked part 522, are first fanning strip and second fanning strip that a disk extends outward.First blocked part 512 can offset with the first block 43a, and second blocked part 522 can offset with the second block 43b, with the rotation angle of common restriction rotating shaft 10 and support 20 relative pedestals 30.
The benefit of this design, referring to Figure 10 and Figure 11, can utilize the fan-shaped angle design of first blocked part 512 and second blocked part 522 of first and second limit element 51 and 52, make support 20 (position as shown in figure 10) when being opened into maximum angle, or when being folded to minimum angles (position as shown in figure 11), first blocked part 512 and second blocked part 522 all can be kept out with the first block 43a and the second block 43b respectively mutually.For example, referring to shown in Figure 12, all can keep out mutually with the first block 43a and the second block 43b respectively in support 20 first blocked part 512 and second blocked part 522 when being opened into maximum angle.
To sum up institute is old, the pivot of the two retaining points of single bolster provided by the utility model, and its major technique thought promptly is provided with two retaining dot structures on single bolster, and does not exceed with the embodiment shown in graphic.In every case the simple change of doing according to this technological thought still belongs among the protection of the utility model claim.
